Description
Technical field
The invention belongs to ground surface material technical field, be specifically related to a kind of asphaltum with high viscosity and production method thereof and device.
Background technology
Drainage road, cement pavement covering bituminous pavement (being called for short " paracetamol "), steel construction bridge floor asphalt concrete etc., all need to use asphaltum with high viscosity.
Drainage asphalt pavement is a kind of high voidage bituminous pavement with water exhaust system.Its Main Function is: because it has high connectivity gap and longitudinal and horizontal drainage measure during the rainy day, road is made to show unlikely ponding, moisture film around mixture particle is also unlikely too thick, thus serve the effects such as anti-sideslip, anti-dazzle, water-mist-proof, reduce the probability of rainy day traffic accident; In addition, the mutual embedded squeezing of this road surface coarse aggregate, skeleton function is obvious, also improves the anti-rut behavior of road.
On cement concrete pavement, Paving Bituminous Concrete surface layer (" paracetamol "), can improve the using function of cement pavement, improve the planeness on road surface.But at the stretching action that contraction or the displacement of cement concrete plate horizontal direction cause, or the flexural tensile stress bottom surface layer, or the vertical shearing stress at cement sheeting seam (crack) place under action of traffic loading, all can produce reflection crack at asphalt concrete pavement, affect the work-ing life of oil mat, destruction is at low temperatures especially remarkable.For effectively preventing, delaying, reduce the appearance of reflection crack, adopting asphaltum with high viscosity to lay one deck stress absorbing layer, is most effective means.
Emerging in multitude of steel structure bridge, makes bridge floor asphalt concrete become the problem of whole world research, and the appearance of asphaltum with high viscosity, is the many again a kind of selections of this problem.
In existing technology, about the technology of asphaltum with high viscosity is a lot, many patent documentations all have report to this, as: CN101457009 B, CN1351096 A, CN1132883 C, CN19990593 A, CN101613515 B etc.The asphaltum with high viscosity production method that these patented technologies are introduced, three kinds of methods can be generalized into: 1. factorial praluction, namely by a whole set of fixing equipment, produce asphaltum with high viscosity at production plant, then deliver to batching plant with special-purpose vehicle, make asphaltum with high viscosity concrete.2. mobile equipment is produced, and namely by a whole set of moveable equipment, produces, after producing asphaltum with high viscosity, is delivered directly to batching plant, make asphaltum with high viscosity concrete near batching plant.3., with whole plant production particulate state asphaltum with high viscosity, that directly renders to batching plant mixes in cylinder, makes asphaltum with high viscosity concrete.Above production method 1,2 all needs huger whole plant, and the transport of special-purpose vehicle and heating repeatedly, not only consume energy greatly and easily cause the aging of material, simultaneously complex process, and the production cycle is long, and relative efficiency is lower.The particulate state asphaltum with high viscosity that method 3 is produced, due to its quality product technical indicator, directly inevitable dependency is not had with the quality index of asphaltum with high viscosity compound, the asphaltum with high viscosity of liquid state must be made, its quality and technical index could be measured, determine whether to prepare qualified asphaltum with high viscosity compound, therefore, particulate state asphaltum with high viscosity, practical application fewer.
Summary of the invention
The object of the present invention is to provide a kind of packed asphaltum with high viscosity of reasonable, simple to operate, safe and reliable, the excellent property of filling a prescription and production method thereof and device.
